The 3 BIG Questions about the Colgate ProClinical 350…
If you are short of time, the answers to the following 3 questions should let you know all you need to about the Colgate ProClinical 350. If we have missed something, let us know in the comments.
If you want more detail, you can read the full Colgate ProClinical C350 review further down the page or watch our video review. You may also like to see our best electric toothbrush page.
1. Is there anything drastically wrong with this toothbrush?
No, not at all. As an electric toothbrush it could serve you very well.
Simple and effective focus on getting the job done at a reasonable price.
We have given a rating of 3/5 to the 350.
2. Which other brushes should I consider?
The 350 is a middle of the range type of brush in my opinion and if wishing to consider other brushes alongside this I offer up the following two suggestions.
You could consider the Colgate 250R. It lacks a cleaning mode, but does the job it needs to.
The second and turthfully better option is from Oral-B. It is the Pro 2 2500. Delivering on a couple of areas where the 350 could be considered to be lacking, it is a very popular option. Find out more in our Oral-B Pro 2 2500 review.
Each have their pros and cons and it is about weighing up what is best for you.
There is one other factor to consider.
The ProClinical 350 comes in two different versions.
There is the ProClinical 350 which comes with a Deep Clean brush head included in the box (view it here on Amazon) and then there is the ProClinical 350 Whitening (view it here on Amazon) which comes with a Max White brush head included in the box.
Two different models, available in different packaging and at slightly different prices, with the only notable difference being the brush head that is included in the box.
Being reviewed here is the standard ProClinical 350 with Deep Clean brush head (which is the slightly more expensive version), but throughout reference will be made to the Whitening model too.

3. Where’s the best place to buy the ProClinical 350?
It is important to note that the Colgate ProClinical C350 has been superseded with the ProClinical 350 (very similar name but the C has been dropped from the model number).
As this review is written, the C350 is still available in some stores, but it’s the newer 350 model (without the C) that you want to go for. It is the newer models that Amazon now has available.
There are quite a few differences between the old C350 and the newer 350 models. The design of the brush, the charging stand and the cleaning modes.
This was all part of a range refresh by Colgate for 2017.
You may still find the C350 available in some stores, but we advise going for the newer version, the 350 (view it here on Amazon).

Pro & Cons
- 2 cleaning modes – Offering a standard cleaning mode along with a more powerful Deep Clean mode that delivered more brush strokes that brushes three times the price.
- Slim and lightweight design – Not quite as slim as the Colgate 250R, the 350 is still a lot slimmer and lighter than its rivals. It is almost featherlight in its design.
- Automatic power off – The brush at the end of the cleaning cycle automatically turns itself off to notify you the clean is over and conserve on power from the battery.
- Battery life – Some 21 days of use is possible from the battery. 42 cleaning sessions lasting 84 minutes. Impressive to say the least.
- Design – It could do with a some more texture to the handle to offer a little more grip.
- Charging stand – Holds the brush but quite a lot of play meaning it could wobble a bit if knocked. It also supports only 220-240v.
Design, Usability, Clean & General Use
I do not like to be influenced by previous reviews, I wish to come to each new brush with an open mind, but it is inevitable, when at the end of this I need to conclude for you whether this brush is worth your hard-earned money or not.
The last Colgate brush that I tried prior to the 350, was the 250+ and quite frankly it was excellent given the size and price. You can read more about it in our ProClinical 250+ Review. It has now been replaced with the 250R, which is not as good.
The 350 here has a more conventional electric toothbrush look to it. I know that sounds a bit weird, but the 250+ was a lot smaller and felt more focused to those who travel.
Overall everything is bigger here with the 350, the height and thickness but actually still relatively light and thinner than the competition.
Compared to other electric toothbrushes the big noticable difference is the angle of the brush head. Where most brush heads are straight or have a very slight angle, here, there is an obvious inwards tilt.
The design is smart here. Whilst the brush is primarily white in colour, there are are couple of red accents that make the brush look stylish and appealing.
Plastic construction all over, the brush handle as a smooth finish to it, with no added grip points.
When wet it may for some feel and be a little more slippery in the hand as a result.
The handle is not covered in buttons or icons. On the front is a power and mode button, the name of 2 cleaning modes, a battery status icon and the Colgate and Omron logos.
The rest of the handle is empty with the exception of a small regulatory sticker on the back of the handle towards the bottom.
A small dimple on the power button offers a natural place for your thumb to rest when in use.
A single press will power the motor inside the brush on and another press will power that motor off.
Just below this power buton, in fact is part of the same button is a mode option option. This has a small raised dot on it, which may help you find the button in low light or if you have visual impairment.
This mode button can be used to switch between the 2 cleaning modes. A simple press is all it needs.
Both of these buttons require a small amount of force but do not appear to be as resistive to touch as many other electric toothbrush buttons. In fact I think this brush requires the least pressure to activate of all the electric toothbrushes I have tried.
When selected the cleaning mode activated is shown by a small white light that illuminates just under the cleaning mode name on the handle.
Those 2 cleaning modes are ‘Optimum’ and ‘Deep Clean’.
Optimum is essentially the daily mode that most will use. The brush pivots from side to side, up and down at a mid speed.
Deep Clean has the brush move up and down at high speed.
When switching between the two modes, the power difference is noticeable not only on the teeth but in the sound from the brush.
When set to Deep Clean the brush offers up to 35,500 strokes per minute. That is more than the Sonicare models from Philips.
The brush head which moves in a variety of directions and can achieve up to 5 times more plaque removal than a manual brush.
Included is a 30 second pacer and 2 minute timer.
At 30 second intervals a pause in the motor alerts you to the need to change quadrant, for an even and effective clean.
After 120 seconds have passed the clean ends automatically and the brush turns itself off.
The recommendation is to clean your teeth for 2 minutes twice a day. You should leave about 45 minutes between eating and brushing if you can. If you want to clean for longer than this you can. Simply power the brush back on for longer. Do be aware too much time spent cleaning your teeth can be damaging too.
Compared to Oral-B brushes the 350 is much quieter, producing an audible humming sound and a strong vibration through the brush handle. Oral-B brushes produce more of a mechanical sound, but do not deliver as much vibration through the handle.
If you have ever used a Philips Sonicare brush the sound of the motor and the vibration is very similar, much because the same sonic technology is used.
After either cleaning mode my teeth felt clean, but particularly after the Deep Clean.
The brush will start any cleaning session on the last cleaning mode it was set to.
In the lower third of the handle is the battery icon and LED, which is great for seeing how much power is left in the built in battery. It will flash when the power is low and iluminat a solid red when on charge. More on this later in the review.
Below this icon and LED is the Colgate and Omron logos.
You are likely more familiar with the Colgate brand than Omron. Colgate is a brand associated with toothpaste, toothbrushes and oral health care, many of us have grown up with the brand.
Omron is a brand more recognised in the healthcare industry too, but they have less of a customer facing focus than Colgate. The Japanese firm specialise in production of various equipment and here the two companies have teamed up to achieve best effect within the dental space.
On the bottom of the handle is a small recess into which the prong found on the top of the charging stand inserts. This then allows the charge to be conducted between the two items.
It does not stand all that securely on this, in fact there is quite a bit of play in the fit between the two items. If knocked generally it wobbles and stays up, despite what feels like not a tight connection.
A single brush head is included with the 350. It is quite common to have 1 brush head included but a second would be nice.
Depending on the package you purchased will depend on the brush head provided. I have the ProClinical 350 which comes with the Deep Clean head, whilst it is possible to purchase the ProClinical 350 Whitening that comes with a Max White head.
User replaceable the brush head should be changed every 3 months. It is always advisable to set some form of reminder to do this, but the blue fading indicator bristles on the head help out here.
Over time they fade from blue to white. Just before or as they get to white, you know it is time to change.
This Deep Clean brush head has soft thin-tipped bristles to sweep along the gumline and power tip bristles that reach into the hard to reach areas. This works to achieve healthier gums and teeth.
4 soft grey rubber bristles act as a cup around the tooth to polish the tooth.
On the back is a tongue cleaner. Run this along the surface of your tongue to refresh the mouth and remove bacteria build up.
I like the smaller size of this brush head, it makes it easy to position and manipulate the brush within the mouth, particularly in the harder to reach areas at the back of the mouth.
The interchangeable nature of the brush heads means that you can swap them out whenever you like.
The 4 brush head options are Deep Clean (included), Max White (included with the 350 whitening) Sensitive and Triple Clean. Any of these 4 heads can be used with the 350 or any other brush in the Colgate range, albeit that some heads like the Deep Clean work best with certain modes.
To change the brush head just pull the head and handle in opposite directions and push together to fit the new one.
The brush itself is water resistant rather than waterproof. This means it will survive life in a wet bathroom and exposed to moisture from the mouth but avoid having the brush reside in water and to prolonged exposure to water. It is not designed for use in the shower.
Overall the 350 is impressive, but it could be argued that there are some omissions.
With the 250+ came a travel cap that protected the head and handle when in transit, but that is not included here and Colgate do not make one.
There is only the one colour option, white.
No pressure sensor is built in either, which is something you do find on Oral-B models as this can be very useful for first time users. That said, if pressure is applied the speed of the motor does reduce until such time as the pressure has ended.
A redeeming feature for some, certainly initially may well be the money back guarantee.
Not really well advertised, you will really only see this on the product box and in the manual.
This essentially allows you to try the brush and return it for a full refund of the purchase price (excluding shipping) if you are not happy. You have 30 days from the date of purchase to try the brush. If you do not like it, send it back within 45 days from date of purchase, providing you have all the original packaging as well as the original receipt.
Details of how to go about this are included in the manual that comes with the brush or you can speak to them on 0800 321 321 32.
And of course as standard you get a year warranty to over you against any failures within that time.

Just how Colgate have managed to achieve the batter life that they have from this brush is outstanding.
I guess it has something to do with the special skills and expertise that Omron bring to the table.
This mid range brush from Colgate is a fraction of the price of some of the premium Oral-B brushes that do not offer battery life as good as this and they have a larger profile.
With my day to day testing I found that I could achieve 84 minutes of cleaning time, that is 3 weeks or 21 days based on 2 x 2 minute cleans each day.
This is based on using the lower powered ‘Optimum’ mode rather than the ‘Deep Clean’ mode, but even with mixed usage you can expect at least 2.5 weeks usage from it.
Simply superb,you cannot ask for more.
Knocking Oral-B brushes as this price out of the water really and more than on par with Sonicare (but even they are larger in hand).
No product description for this brush be that on Colgate’s own web page or any of those retailers selling it really explain how much battery life is available. Why not when it is this good?!
The automatic power off feature certainly helps here to get the most power from the brush.
This may well be a frustration to some, but not to me.
When the battery is nearly depleted the battery light will illuminate red to let you know. I would suggest you can still get 3-4 cleaning sessions out of the brush even when it begins to tell you it is low.
When it comes to recharging, a stand is included in the box.
It is a 2 pin charger designed to connect to sockets often found in bathrooms. Supporting 220-240v it does not have the global support for lower voltages from 100v like the Sonicare chargers do.
You can purchase 2 pin to 3 pin adapters so that the brush can be charged from a normal mains socket found here in the UK.
The dock is white in colour with the Colgate logo on the front.
A small prong protrudes from the top of the stand, it is this that sits just inside the base of the brush and passes the charge inductively to the battery inside the brush handle.
I mentioned earlier that when on the stand the brush is a bit wobbly with a bit of movement if touched. Despite the wobble in the connection it generally stays upright.
When charging the LED on the brush handle illuminates red, going off when fully charged. This charging process takes about 10 hours.
Leave it on during the day or overnight, it is safe. It is a slow charging process.
In fact you can leave the brush on charge all the time when not using it.
Probably best to run the battery down every 6 months to ensure you get the maximum life from it.
Summary of Battery Life
- 84 minutes of usage time or 21 days usage based on 2 cleans a day
- A charging stand is included in the box
- The brush is a bit wobbly when on the stand
- Takes about 10 hours to charge fully
- An LED illuminates red when the brush is charging
- Works on 220 240 volts
The RRP of this brush is £59.99.
Whilst that might be the suggested retail price, the reality is that normally this is not the price that electric toothbrushes sell for. More often than not the price is about 50% of that.
Replacing the ProClinical C350, this refreshed model will settle for on average £30-35, although some may choose to price at the RRP.
We are going to assume though that by the fact you are reading this review, you are a bit of a savvy shopper and are looking to get the best value that you can.
You may well be keen to get it at the lowest price possible price.
Is the RRP justifiable? Possibly. You can get better if spending a whole £60.
Is a discounted price of £30-35 good value? Yes I would say so. It is on par with comparable brushes.
If you can get is for less than £30, snap it up. I don’t believe you will be disappointed.
The 350 comes supplied with either a Deep Clean or Max White brush head, both of which need replacing every 3 months.
Replacement heads can be purchased in packs of 2 or 4 (depending upon the ones you chose) and are priced on average between £10-£18.
Generally speaking the 4 pack is more cost effective and many retailers sell the Deep Clean brush head that comes with the 350 for £10. This gives a per head cost of just £2.50.
Using the average cost (based on one user) and ownership over 3 years, the ProClinical 350 will cost £60 or 5p per day to own.
This price does exclude the cost of water, toothpaste and electric to charge it, but you get a rough idea and is one of if not the cheapest decent electric toothbrushes available at the moment.
There is a good chance the brush will last longer than the 3 year period and using the same brush handle but switching heads with other users in your household will only help bring the cost down and drive more value from it.
Please note that all costs quoted are approximates and prices will vary based on location, supplier, time of purchase. These figures should not be relied on as hard fact but as a guide, based on real information at the time of writing.
Summary of Price
- Recommended retail price of £59.99
- Generally available for around £30-35
- Brush heads typically available for £10 per pack of 4 or £2.50 each
- Works out at around 5p per day over 3 years
- Share brush handle with another user to extend value
Reliability & Long Term Use
You can be safe in the knowledge that whilst he likely working life of the 350 from Colgate is likely longer than the 2 year warranty, should something go wrong during that time you are covered, unless its user damage.
On the whole electric toothbrushes from any brand are reliable, but to date here at Electric Teeth we have received fewer complaints about Colgate compared to some other brands.
Lab tests or durability tests are not something we do and it is not possible to test every toothbrush day in day out and report back on how they fare. However we take reliability seriously and always comment on where we think weaknesses are.
When testing we really try to look for flaws or weaknesses in all of the products we test.
After a few weeks with the ProClinical 350 I can’t say I have found any real problem areas in terms of reliability, there are few things to go wrong with it.
The whole brush feels robust and the sealed design offers few cracks in the body for water ingression or possible weakness.
The power button is firm and responsive too.
As a package this brush does exactly what you would want and or expect of it.
Your are not sold a load of exaggerated facts and provided with useless items in the box.
Brush handle, head, charger, instructions and you are away.
A smart design, a good clean and a decent battery life, what is not to like?
I have given the 350 a rating of 3 out of 5. In many respects is deserves 3.5-4, but we don’t do half ratings and for me, there is just something the 350 lacks to really make it worth the 4 star rating.
Oral-B brushes may have inferior battery life but the sprinkle of colour and features such as a pressure sensor become present at this price point, little extras to seal the deal and become more appealing.
The Pro 2 2500 is a very good brush to consider and I think all round better value.
But, if you think the 350 is for you, I can assure you that there are a lot worse brushes out there and you will unlikely be disappointed.
